Mineral resources of the northern and central San Andres Mountains, White Sands Missile Range, New Mexico
— Virginia T. McLemore

There are four types of deposits in northern and central San Andres Mountains (Rio Grande rift (RGR), copper-silver (± uranium) vein, vein and replacement deposits in Proterozoic rocks, and Proterozoic talc deposits) in five districts: Mockingbird Gap, Salinas Peak, Grandview-Sulfur Canyons, San Andrecito-Hembrillo, and San Andres Canyon districts. All of these districts are on the White Sands Missile Range and have been withdrawn from mineral entry since the 1940s. It is estimated that <$53,000 worth of Au, Ag, Cu, Zn, Pb, Bi , W, Fe, barite, fluorite, and talc were produced from the five districts in 1900-1948.
